CVE-2025-6076 Overview
CVE-2025-6076 is an unrestricted file upload vulnerability in Partner Software's Partner Software application and Partner Web application. The flaw resides in the reports tab, which fails to sanitize uploaded files. An authenticated attacker can upload a malicious file and execute it on the host, compromising the device. Because the affected software runs as SYSTEM by default, successful exploitation grants the attacker the highest level of privileges on Windows hosts. The vulnerability is network-accessible and requires only low-privileged authentication, making it suitable for post-access lateral movement and persistence operations.
Critical Impact
Authenticated attackers can upload arbitrary files through the reports tab and achieve code execution as SYSTEM, resulting in full host compromise.

Technical Details for CVE-2025-6076
Vulnerability Analysis
The vulnerability is an Unrestricted File Upload flaw in the reports tab of Partner Software's Partner Software and Partner Web applications. The application accepts user-supplied files without validating file type, content, or extension. An authenticated attacker can upload an executable payload or script that the host subsequently runs. Because the application service runs under the SYSTEM account by default, attacker code inherits full administrative privileges on the Windows host.
Exploitation results in compromise of confidentiality, integrity, and availability. The attack vector is network-based, exploitation complexity is low, and only low-level authenticated access is required. The EPSS score is 0.658% (percentile 46.684) as of 2026-06-23, indicating moderate predicted exploitation likelihood relative to all tracked CVEs.
Root Cause
The application's upload handler on the reports tab does not enforce server-side validation of file extensions, MIME types, or content signatures. There is no allowlist of permitted file formats and no isolation of uploaded content from executable directories. Combined with the service running as SYSTEM, this design choice converts a file upload feature into a full remote code execution primitive for any authenticated user.
Attack Vector
An attacker first obtains valid application credentials, which may be acquired through phishing, credential stuffing, or insider access. The attacker then authenticates to the Partner Software or Partner Web interface and navigates to the reports tab. From there, the attacker uploads a malicious file such as a script, executable, or web shell. Once the file is processed or invoked by the host, code executes in the context of the SYSTEM account. Refer to the CERT Vulnerability Report #317469 for additional technical context.
Detection Methods for CVE-2025-6076
Indicators of Compromise
- Unexpected files written to Partner Software application directories, particularly within paths used by the reports upload feature
- New or modified executables, scripts, or web shells with recent timestamps owned by the Partner Software service account
- Child processes spawned by the Partner Software service running as SYSTEM with command lines invoking cmd.exe, powershell.exe, or scripting hosts
Detection Strategies
- Monitor file creation events in Partner Software installation and upload directories for non-report file types such as .exe, .dll, .bat, .ps1, .aspx, or .jsp
- Alert on process creation chains where the Partner Software service is the parent of interpreters or LOLBins
- Correlate authentication events on the Partner Web application with subsequent file write and process execution events
Monitoring Recommendations
- Enable detailed audit logging for file uploads on the reports tab and forward logs to a central SIEM
- Track service account behavior for the Partner Software process and alert on deviations from baseline
- Review web server and application logs for POST requests to upload endpoints from unusual user accounts or source IP addresses
How to Mitigate CVE-2025-6076
Immediate Actions Required
- Apply the vendor-supplied patch documented in the Partner Software Release Info as soon as possible
- Restrict network access to the Partner Software and Partner Web interfaces to trusted management networks only
- Audit and rotate credentials for all Partner Software application accounts, prioritizing accounts with access to the reports tab
- Reconfigure the Partner Software service to run under a least-privilege account rather than SYSTEM where supported
Patch Information
Partner Software has published release information addressing this vulnerability. Administrators should consult the Partner Software Release Info and the CERT Vulnerability Report #317469 for fixed versions and upgrade procedures.
Workarounds
- Limit access to the reports tab to a minimal set of trusted administrative users until patching is complete
- Place the application behind a web application firewall configured to inspect and block uploads of executable content
- Implement host-based application control to prevent execution of unauthorized binaries written into Partner Software directories
# Configuration example: restrict service account privileges on Windows
# Replace SYSTEM with a dedicated low-privilege service account
sc.exe config "PartnerSoftwareService" obj= ".\PartnerSvcAccount" password= "<StrongPassword>"
sc.exe stop "PartnerSoftwareService"
sc.exe start "PartnerSoftwareService"
